All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad, sallallaahu ʻalayhi wa sallam, is His slave and Messenger.
The basic principle is that there is no harm in registering and making name lists of the refugees. Rather, the doer earns rewards for that good deed because this is part of helping these refugees and facilitating their affairs. The fact that the concerned officials may gather young men and women in one place does not make registering or helping them unlawful.
We believe that there is no religious impediment to your work as long as it does not involve a violation of Islamic law such as being alone with a non-mahram (permanently unmarriageable) man in seclusion or prohibited intermixing between men and women and it is confined to registering the names and giving them the needed instructions and guidelines.

Allaah knows best.
